Hi Ranchers,
I passed my 1z0-830 (
Java 21) exam a few days ago, with a score of 88%. The questions were similar to the Standard exams provided by the Enthuware simulator, and I'd say even slightly easier.
I used Hanumant Deshmukh's Java 17/21 book (
https://enthuware.com/books/287-java-17-21-certification-fundamentals) to prepare and the Enthuware simulator, and they were more than enough, nothing else needed.
No surprises really, quite a few questions related to Streams, enums and primitive operations, a few on records,
pattern matching, enhanced switch. Didn't get any on generics, localization or java.time surprisingly. Got a couple on concurrency, virtual threads, I/O. Got one on JImage. Got one on modules.
